4stropped bybein-g placed between adouble and face butted endless beltstrop 11. The belt 11 is mounted onpulleys v12 and 13, the former ofwhich is power driven, being mounted for. that purpose on a rotary shaft14, .which is provided with suitable bearings in the frame 15 of themachine. `13 an idler, and is mounted on a vertically.. disposed shaft16. The pulleyflf is pro` vided witha bushing .17 to forma bearing forthe diminished section of the shaft 16,'

The pulley as shown bestin Fig. of the drawings.

rl `he shaft 16 is upbent from a'threaded` ortlon 18, the threadswhereof are -engagedby the threads of anut 19. The end of the portionl18 beyond the threaded section 'is provided with a guide block 20,'whic eX- tends `within the' rectangular tubul` ramevr 15. By means` ofAthis constructionitis ob- Vious that the separation of` thjeypulleys 12y and 13 may be ivaried` 'at-twill, therebv increasing or. diminishingthe tensii on the l belt `11. A The belt 11 is illustrated in the drawinas composed of two duplicate belts, ithe hair sides of which are`laidtcgether andthey esh sides of .which are outwardly disposed.

This arrangement of thebelts forms a very convenient manner ofprotecting the same against settlement of dust on the surfacethereoforming-.a grit unnatural and unde; sired. This .is particularlytruev when the strop surfaces are dressed or otherwisev pre;

pared. v v -f i --As shown inFig, 7 of the drawings, the

frame is provided .with a hand hold 21,` which may be grasped by thehand of the' operator, andthe shaft 14 is providedwith` dit ssl.

a Acrank attachment 22. The attachment l22 4 is mounted on the' Vsquaredend 23 of the shaft 14 sothatthe handle- 21 may" be `ro.

tated to drive thebelt 11, 11. In thisl manner thev machine isVhand-loperated,j landf manipulated.

The blade A1 Ais pl'aedwiithin a cup heide-r 24. The ciip'hoidef 24g-fismountedfon a stationary' arm 25, being provided with a sleeve arm 26`whichffii'tsfover the "armf25' 'and is secured thereo I armjis providedwith ajsc'rew threaded endy section 28, having afshoulder 29 t o` restagain'stthe side ofjtheframe 15y when the tions in'thesa'idyramemsshownin, yiglof the drawings. The fed section 28 is screw' threaded toreceive a nut whereby the end section and the arm 25'lconnectedtherewith are clamped rigidly in adj ustedaposition. The sleeve 26 andthe clip holder 24 connected therewith are rocked to throw theblade AVfrom side to side on the pivotal center of the arm 25, forcingoutwardly alternately the said belts 11, 11. The lateral swing oftheblade when mounted in the clip holderl 24 is equal on each side of thepivotal center of the said arm, and this because of the fact that theoscillation of the sleeve 26 is mechanically produced. The sleeve 26 hasan off set arm'31 extended fromthe lower end of the said sleeve. The arm31 is loosely'c'onnected by means of a screw 32 with the eye leted endof a connectin 'rod 33. The rod 33 is bent to any suitab e shape, and issecured to the pulley 12 by a screw 34 set out from the center of thesaid'pulley 12. The disposition of the screw 34'with reference to fthecenter of the pulley 1'2 regulates t-he throw of the arm 31 and thesleeve 26 connected therewith. The connection between the screw 34 andthe rod v33, it will be understood, is a loose `or pivotal connection.v 1. A'

When using the short or safety type of blade, the same is introducedwithin the clip holder 24, much in the same manner as the l, same typeofblades are placed within the `hand stropping devices now 1n use. .When

-manipulated manually, the operator so disposed, and when the machine isbeing the handle 21, as shown .in Fig. 7 drawings, and turns the crank22 rapidly or slowly, as desired. The turning of the crank 22 when fastto the shaft 14 rotates the pulleys 12 and 13 carrying the double belts11, 11 constantly in one direction. 'The pulley 12 carries the screw 34about the v center of the said ulley, and by reason of l'GIS theconnectin ro 33 connecting the said pulley yand s eeve 26, the saidsleeve is rocked on the arm 25 carrying alternately Ato opposite sidesof the median line of the belts 11, 11, the holder 24 and fblade Amounted therein. 'It will also be observed that the arm 25 is disposedin angular relation to the travel `of the belt, :as seen in Fig.

:7. The angular disposition of the arm 25' is varied by loosening thenut 30 and setting-y the arm 25 to the desired position, and then thesaid nut 30. The. connection ti htenin v of the roi? 33'with the arm 31and the pulley 12 is suiciently loose to provide for a suitable'anddesired'adjustment of these'parts without cramping. It is obvious thatwith the operation of the crank 22 the blade 'A is alternately forcedagainst the outer and inner belts l11,11, supporting` the same andreceiving on the edge of the blade the full tension of the said belts.Also, by reason' lof/the inclined disposition of the arm 25jit will beobserved that the blade is constantly' the tray 35 may be slidablymounted 48 that the disk 46 is secured.

and steadilyheld in the most' favorable posi-l tion for 'receivin themost perfect edge. When the st-ropplng has proceeded to the desiredextent the machine is arrested .and the blade A withdrawn from the clipholder 24.

.When the long blade or exposed blade type of razor isstroppedfthe-blade is inserted between the clip holder 24 in the same`manner as that above described with reference to the short or safetyrazor type,\but there `is provided a further handle holding device ortray 35. The tray 35 is provided with a supporting rod 36. The rod 36 isprovidedvatthe lower end with a slide 37. The slide 37 is locked inposition onthe frame 15 :by means of a clamp 38, the sa'id' clamp beingat will forced against the frame 415 by setting u the screw 39. Seekarticularly Fig. 8 o the drawin for t is construction. By

it will be seen that the slide-37 may be ad! means oft is Vconstructionjusted lengthwise on 1tliessframe 15, tofsuit the disposition oftheblade/A and the handle B t ereof'.. .If desired, means for retain. ingthe handle B in the tray 3 5 may be provi ed. Also, for convenience `ofackinlg, ont e rod 36 and secured lengthwise thereon by-a set screw 40,as seen in Fig. 7 of the draw-A ings. The operation, as far as stroppingis concerned, Vwhen using the machine forsharpening razors of the longblade type, is

similar to the operation above d ribed as `when using the machine toSharpe blades of the short or safety razor type.

When thev machine is attached for\me chanical manipulation there isprovided a stand 41,'-upon which'is suitably mounted -a supporting frame42, between the 'arms whereofV is clamped the frame15, using for thatpurposeVt a wing nut" 43. Suitably mounted :tlieMs'Etand 41 is anelectric motor 44, upon the amature shaft of which is mounted a suitablefriction. pulley 45. The pulley 45'4is arranged and provided to rotateon alfriction4 disk 46 to thereby rotate the'shaft 14. The shaft 14 isoperatively connected `with the disk 46 by a shaft 47 The shaft 47 is/clampedin' fixed relation to the disk 46 by means of a screw-nut 48.'The shaft 47 is provided with a pivotal extension 49,v which 1srotatively mountedin a standard 50 suitably arranged d 'xedly secured onthe. stand Q41. Th shaft 47 may be adjusted vertically by means of acollar 51, which is slidably mounted on the e'xtension 49 of the saidshaft, and which is fixedly secured thereto by means-of a set screw 52.-AIt is betweenthe collar land the nut When the machine is mounted -inconnec-v v vtion with the 4mechanical means above described, the oconsists in holder 24, and turning on the electric current for the motor44. This having been accomplished, and the motor having gatheredheadway, the barber is at libert-y to attend to any other office in hisprofession whilefthe' razor is being stropped. Further, the stropping-isexecuted more evenly and `more quickly thanby the hand methodat 'presentused. Further, it Will be seen that\ the stropping may be continued toan extent beyond 'the endurance of the ordinary operator, thereby-givingto the blade a finer and more perfect edge than imparted by thenect'ingl 4usual hand method.

Having thus described my invention, what Iclaim'as new and desire tosecureby Letters Patent is 1. A razor stropping machine, comprising aplurality of overlaid face-bu'tted endless stropping belts; a pluralityof pulleys to'supportsaid belts; a frame to support `said pulleys; ablade holding device disosed between said belts and supported on saidframe; lrneans for adjusting said blade holding device in inclinedrelation to said belts; an arm laterally extended from said Vbladeholding device; a pitman rod 'consaid arm and one of .sai pulleys torock t e said blade holding device; and a' tray supported on said framefor holding the handle of a folding razor when the blade thereof is heldby said blade holding device'.

2. In a. razor stropping machine a straight bar frame provided at theone end thereof with a. holding handle; a plurality of shafts mounted onsaid frame and extended perpendicularly therefrom; a plurality ofpulleys mounted on said shafts in `Tit-ned relation; a pluralityof-overlaid face butted endless stropping belts mountedon said pulleys;a blade holder pivotally mounted in said frame and extended between.lsaid belts in an inclined position therein, said= blade holder having anextended arm; a pitnian ypivotally connected with the said pulleys at apoint relnoved from the center tllereof and the said arm extended from:said blade holder; and means 'connected `with one of said. pulleys forrotating the saine to clrive the said belts and reciprocate vthe saidpitman.

In testimony whereof I have signed this specification in the-presence oftwo subscriblng Witnesses.
